And, as it is shown in figure 9, by the insulating element 16 of fixture 51,52 clamping by the end of insulation linking part 16c side towards the radial outside of armature core 7 and insulation linking part 16c opposition side end towards in the way of the radially inner side of armature core 7 in the axial direction axial one end open portion with teeth groove S arranged opposite.Now, insulation axially extending along armature core 7 of linking part 16c.And, by not shown instrument, make insulating element 16 moving axially with respect to fixture 51,52 along armature core 7, thus by insulating element 16 from the axial one end open portion of teeth groove S along the inside being axially inserted into teeth groove S of armature core 7.Now, the end (that is, the end of the radially inner side of opposed portion 16a, 16b) of the insulation linking part 16c opposition side on a pair opposed portion 16a, 16b is in being axially inserted into slit 14.It addition, as shown in Figure 10, the end of the insulation linking part 16c opposition side on 2 opposed portion 16a, 16b can be projected into the inner side of armature core 7 from slit 14.In addition, as mentioned above, insulating element 16 is by being clamped by fixture 51,52, thus the width W1 of the circumferencial direction that its width W4 is than teeth groove S is narrow, and the width W5 of the end of the insulation linking part 16c opposition side of this insulating element 16 is narrower than the width W2 of the circumferencial direction of slit 14.Therefore, insulating element 16 can be inserted into the inside of teeth groove S with the medial surface of teeth groove S and the medial surface (that is, tabular surface 13b) of slit 14 under the state not contacted.
And, insulating element 16 is inserted in teeth groove S, is run through by teeth groove S in the axial direction and state that peristome from the axial both sides of teeth groove S is prominent to axial both sides until being in.The restraining forces that the insulating element 16 reason fixture 51,52 being inserted in each teeth groove S produces releases, and as shown in figure 11, under the elastic force effect of insulating element 16, opposed portion 16a, 16b open and be separated from each other in a circumferential direction.Therefore, opposed portion 16a, the end of insulation linking part 16c opposition side of 16b, i.e., the end of radially inner side of opposed portion 16a, 16b contacts with the medial surface of slit 14.Thus, by the frictional force between opposed portion 16a, the end of the radially inner side of 16b and the medial surface of slit 14, easily insulating element 16 is maintained at the inside of teeth groove S.
Then, carry out insulating element deformation operation, make insulating element 16 deform and against the medial surface of teeth groove S.As shown in figure 14, in insulating element deformation operation, the bar-shaped heating tool 61 of cross sectional shape cross sectional shape (cross sectional shape orthogonal to the axial direction) little Yi Quan (the little amount corresponding with the thickness of insulating element 16) than teeth groove S is used.Heating tool 61 can be by not shown driving means moving axially along armature core 7.And, it is inserted into the inner side of each insulating element 16 by would be heated to the heating tool 61 of predetermined temperature such that it is able to make each insulating element 16 deform and against the medial surface of teeth groove S.Now, heating tool 61 is inserted in teeth groove S from the axial one end open portion of teeth groove S, and be inserted into teeth groove S about 1/3rd the degree of depth.Thus, in the axial side, one end open portion of each teeth groove S, insulating element 16 is formed as against the shape of the medial surface of teeth groove S, so the inner space of insulating element 16 expands in a circumferential direction.
Then, as shown in Figure 12 A and Figure 12 B, carry out opening operation, will open in a circumferential direction from teeth groove S to the axial one end of axially projecting insulating element 16.In opening operation, on the axial one end of the prominent insulating element 16 in the axial one end open portion from teeth groove S, crimping is heated to the thermoforming device 71 of predetermined temperature.Thermoforming device 71 is connected by the multiple thermoforming portions 72 being shaped generally as corner taper and forms.It addition, in Figure 12 A and Figure 12 B, only illustrate 1 among multiple thermoforming portion 72.Top ends 72a in thermoforming portion 72 is formed as the shape corresponding with the shape of teeth groove S, it is possible to be inserted in teeth groove S.Further, the width of circumferencial direction of the width ratio teeth groove S that the position of the base end side in thermoforming portion 72 is formed as its circumferencial direction is big.Additionally, multiple (in present embodiment being 30) thermoforming portion 72 is in a circumferential direction across predetermined interval configuration, so as to be inserted simultaneously in the teeth groove S of.
As illustrated in fig. 12, it is heated to move by the way of the thermoforming portion 72 of predetermined temperature is abutted with the inner side from the axial one end being axially facing the insulating element 16 prominent with the axial one end open portion from teeth groove S by the not shown driving means of thermoforming device 71.It addition, the axial one end of the insulating element 16 prominent from the axial one end open portion of teeth groove S is the end of the side being inserted into heating tool 61 described deformation operation.And, as shown in Figure 12 B, thermoforming portion 72 is pressed against the inner side of insulating element 16, until its top ends 72a is inserted into the inside of teeth groove S from the axial one end open portion of teeth groove S.Thus, the axial one end of prominent from the axial one end open portion of teeth groove S insulating element 16 opens in a circumferential direction according to the outer shape in thermoforming portion 72.That is, the axial one end of the insulating element 16 highlighted in the axial one end open portion from teeth groove S is formed with the portion of opening 44 opened in a circumferential direction.
Open in operation in present embodiment, as shown in FIG. 13A, when on the axial one end of the insulating element 16 being inserted on circumferencial direction in the teeth groove S of, portion 44 is opened in formation, thermoforming portion 72 is departed from from armature core 7 in the axial direction by driving means.Then, thermoforming portion 72 moves 1 teeth groove in a circumferential direction by driving means and divides, and as shown in Figure 13 B, is similarly formed on the axial one end being inserted into remaining insulating element 16 in the teeth groove S of 1 by thermoforming portion 72 and opens portion 44.
Then, as shown in figure 15, carrying out conductor and insert operation, the inner side of the insulating element 16 in being inserted into teeth groove S, from being axially inserted into multiple segmented conductor 17.In conductor inserts operation, 2 line parts 17a, 17b of segmented conductor 17 are inserted respectively in 2 the teeth groove S being separated by predetermined quantity in a circumferential direction.Line part 17a, 17b are inserted into the inner side of insulating element 16 from side, the portion of opening 44.It addition, segmented conductor 17 moving axially with respect to armature core 7 along armature core 7, until the top ends of line part 17a, 17b is projected into the outside of teeth groove S from the axial other end peristome (that is, opening the peristome of opposition side, portion 44) of teeth groove S.
Then, bending process is carried out, by the top ends bending in a circumferential direction of prominent for the axial other end peristome from teeth groove S line part 17a, 17b.As shown in Figure 5, in bending process, when there are insulating element 16 between the chamfered section 15 that each line part 17a, 17b are arranged on the opening edge of the axial other end peristome of teeth groove S, chamfered section 15 is pressed and along the circumferential direction bending near this chamfered section 15.And, the top ends bending in a circumferential direction of each line part 17a, 17b, thus the top of each line part 17a, 17b is configured on the position adjacent with connected other line parts 17a, 17b respectively.
Then, connection operation line part 17a, 17b electrically connected is carried out.In connecting operation, by welding, each line part 17a, 17b are electrically connected with other line parts 17a, 17b respectively.Thus, multiple segmented conductors 17 form sectional wind 18, so complete stator 6.
Then, the effect of the manufacture method of the stator 6 of present embodiment is illustrated.
The insulating element 16 formed in insulating element formation process is cross section substantially C-shaped, so easily making the end of the insulation linking part 16c opposition side on 2 opposed portion 16a, 16b, i.e. the end of the peristome side of C-shaped is close.Therefore, insert in operation at insulating element, while the width of the end easily reducing the insulation linking part 16c opposition side of insulating element 16, easily opposed portion 16a, 16b thickness direction on reduce the width of this insulating element 16.Thereby, it is possible to easily make insulating element 16 deform (flexure) become the narrow width of the circumferencial direction than teeth groove S.
As it has been described above, according to present embodiment, it is possible to obtain advantages below.
(1) insulating element 16 owing to being formed in insulating element formation process is cross section substantially C-shaped, it is possible to easily make the end (top ends) of the insulation linking part 16c opposition side on 2 opposed portion 16a, 16b, i.e., the end of the peristome side of C-shaped is close to each other or leaves.Therefore, it is possible to while easily making the reduced width of the end of the insulation linking part 16c opposition side of insulating element 16, reduce this insulating element 16 opposed portion 16a, 16b thickness direction on width.Become the width W1 of circumferencial direction than teeth groove S narrow thereby, it is possible to easily make insulating element 16 deform (flexure).Therefore, in insulating element inserts operation, when insulating element 16 is inserted in teeth groove S, it is possible to suppression insulating element 16 contacts with the medial surface of teeth groove S.It is as a result, it is possible to avoid insulating element 16 to damage, even if so in the case of being formed insulating element 16 by the insulant 41 that thickness is thin, it is also possible to guarantee the insulating properties between segmented conductor 17 and armature core 7.Further, since be formed without the position of insulating element 16 overlap in the inside of teeth groove S, it is possible to suppression results from the decline of fill-in ratio of insulating element 16.Thereby, it is possible to while the insulating properties guaranteed between segmented conductor 17 and armature core 7, it is possible to suppression fill-in ratio declines.
(2) in conductor inserts operation, by segmented conductor 17 to be inserted into the inner side of insulating element 16 from side, the portion of opening 44 such that it is able to segmented conductor 17 to be easily inserted into the inner side of insulating element 16.Therefore, it is possible to the top ends of suppression line part 17a, 17b is damaged to insulating element 16.Its result, contributes to reducing the thickness of insulating element 16.
(3) in chamfering process, chamfer machining is implemented by the opening edge in the axial both ends open portion to teeth groove S, even if thus the insulating element carried out later inserts in operation, insulating element 16 clips the opening edge in the axial both ends open portion of teeth groove S, it is also possible to suppress this insulating element 16 impaired because of the opening edge in the axial both ends open portion of teeth groove S.Therefore, contribute to reducing the thickness of insulating element 16.
(4) in deformation operation, when insulating element 16 is along the medial surface deformation of teeth groove S, the space of the inner side of insulating element 16 expands in a circumferential direction.Therefore, it is possible to more easily segmented conductor 17 to be inserted into the inner side of insulating element 16, it is possible to the top ends of suppression segmented conductor 17 causes damage to insulating element 16 further.Thus, it helps reduce the thickness of insulating element 16.
(5) in insulating element inserts operation, when insulating element 16 is inserted in teeth groove S, 2 opposed portion 16a, the end (that is, the end of the insulation linking part 16c opposition side on 2 opposed portion 16a, 16b) of radially inner side of 16b are inserted into the inside of slit 14.And, as long as insulating element 16 is formed as when deforming in operation the medial surface along teeth groove S and having deformed, 2 opposed portion 16a, the end of radially inner side of 16b are configured in the inside of slit 14, it becomes possible to by the whole covering of medial surface of teeth groove S.Therefore, as in the present embodiment, when rotor opposed portion 13a top end face (i.e., tabular surface 13b) length L1 of radial direction longer than overhang L2 of the circumferencial direction of rotor opposed portion 13a time, the scope of end of the radially inner side of 2 opposed portion 16a, 16b can be configured after deformation operation radially expanded.Therefore, it is possible to the dimensional accuracy of the length (that is, length L4) between the end of the end of the insulation linking part 16c side of relax on insulating element 16 2 opposed portion 16a, 16b and insulation linking part 16c opposition side.It is as a result, it is possible to reduce the manufacturing cost of stator 6.
(6) winding (sectional wind 18) it is made up of segmented conductor 17, it is possible to more improve fill-in ratio.It is as a result, it is possible to reduce the volume of the motor 1 of per unit output.It addition, the opening edge portion in the axial both ends open portion of teeth groove S implements chamfering respectively and forms chamfered section 15.Therefore, during line part 17a, 17b of bending segmented conductor 17 in a circumferential direction, it is possible to the insulating element 16 between the opening edge of the axial peristome that suppression is clamped in line part 17a, 17b and teeth groove S is damaged by this opening edge.
(7) in stator 6, the insulating element 16 of lamellar can easily make the end of the insulation linking part 16c opposition side on 2 opposed portion 16a, 16b each other, i.e. 2 opposed portion 16a, 16b the end of radially inner side close to each other or separately.Therefore, it is possible to while the width that the end of the insulation linking part 16c opposition side reduced on insulating element 16 is each other, easily opposed portion 16a, 16b thickness direction on reduce the width of this insulating element 16.Therefore, it is possible to easily insulating element 16 is deformed (flexure) become the narrow width of the circumferencial direction than teeth groove S, so when insulating element 16 is inserted in teeth groove S, it is possible to suppression insulating element 16 contacts with the medial surface of teeth groove S.Its result, the damage of insulating element 16 is inhibited, even if so in the case of the thickness of insulating element 16 is thin, it is also possible to guarantee the insulating properties between segmented conductor 17 and armature core 7.Further, since be formed without the position that insulating element 16 overlaps in the inside of teeth groove S, it is possible to the fill-in ratio that suppression is caused by insulating element 16 declines.Thereby, it is possible to while the insulating properties guaranteed between segmented conductor 17 and armature core 7, suppression fill-in ratio declines.
It addition, in stator 6, as long as the end of insulating element 16 radially inner side that is formed as 2 opposed portion 16a, 16b is configured to the inside of slit 14, it becomes possible to by the whole covering of medial surface of teeth groove S.Therefore, as present embodiment, the top end face of rotor opposed portion 13a is (i.e., tabular surface 13b) length L1 of radial direction longer than overhang L2 of the circumferencial direction of rotor opposed portion 13a time, the scope of the end that can configure the radially inner side of 2 opposed portion 16a, 16b on each insulating element 16 expands diametrically.Therefore, it is possible to relax the dimensional accuracy of the length of the radial direction of opposed portion 16a, 16b.It is as a result, it is possible to reduce the manufacturing cost of stator 6.
(8) by making motor 1 possess the rotor 21 of commutation polar form such that it is able to the quantity of the Magnetitum 35 being installed on rotor 21 is reduced half.Therefore, it is possible to reduce the manufacturing cost of this motor 1.Further, since rotor 21 has space 36, it is possible to alleviate the weight of rotor 21, it is possible to alleviate the weight of whole motor 1.
(9) when the restraining forces of the fixture 51,52 etc. bent by this insulating element 16 in insulating element inserts operation disappears, due to insulating element 16 original shape to be returned under the elastic force effect of self, so 2 opposed portion 16a, 16b separate the most in a circumferential direction.Therefore, on each insulating element 16, the most separate 2 opposed portion 16a, 16b are in medial surface (that is, the tabular surface 13b) contact of the inside of the slit 14 the narrowest for width W1 of the circumferencial direction of the width ratio teeth groove S of circumferencial direction with slit 14.Like this, it is inserted within slit 14 2 opposed portion 16a, 16b and contacts with the medial surface of slit 14, thus insulating element 16 is difficult to move relative to armature core 7, so easily keeping the state being arranged in the inside of teeth groove S.Therefore, it is possible to easily carry out the operation carried out after insulating element inserts operation.
(10) in the case of the insulating element being formed as tubular as in the past is inserted in teeth groove, it is desirable to the insulating element of tubular has higher dimensional accuracy.Relative to this, in the insulating element 16 of present embodiment, the end of the insulation linking part 16c opposition side on 2 opposed portion 16a, 16b is inserted in the slit 14 of the radially inner side opening of the inside of teeth groove S and armature core 7, it is possible to relax the dimensional accuracy (can take bigger dimensional tolerance) of the length of the radial direction of insulating element 16.It is as a result, it is possible to more reduce the manufacturing cost of stator 6.
(11) inserting in operation at insulating element, 2 opposed portion 16a of insulating element 16, the end (top ends) of insulation linking part 16c opposition side of 16b are inserted in slit 14.Slit 14 is to the inside of teeth groove S and radially inner side opening.It is to say, slit 14 connects and to the radially inner side opening of armature core 7 with corresponding teeth groove S-phase.Therefore, when insulating element 16 is bent, even if the length of the radial direction of insulating element 16 (radial direction of armature core 7) increases, it is also possible to easily insulating element 16 is inserted in teeth groove S.
